The Importance of Building System Cleaning and Disinfection – Hospitality

Tank cleaning and disinfection: Legionnaires’ disease, a potentially fatal form of pneumonia caused by Legionella bacteria, first gained notoriety in 1976 following an American Legion Conference in Philadelphia. Since then, it has remained a significant public health concern, particularly in buildings with intricate water systems. Legionella bacteria thrive in water sources, especially when conditions allow for their growth and dissemination. While Legionnaires’ disease cannot be transmitted from person to person, it poses a serious threat, especially to high-risk groups such as males over 45 years old, heavy smokers, alcoholics, and individuals with weakened immune systems or underlying health conditions like kidney disease or cancer.

Statistics suggest that Legionnaires’ disease affects thousands annually, with a significant portion linked to contaminated building water systems. Understanding the causation chain is crucial: Legionella must infiltrate a water system, proliferate under favourable conditions, disseminate in aerosol form, and ultimately be inhaled by susceptible individuals. Factors such as nutrient availability, temperature, and time play critical roles in facilitating Legionella growth and dissemination.

To mitigate the risk, effective cleaning and disinfection of hot and cold water systems are paramount. The Health and Safety Executive (HSG 274 p42) recommends controlling Legionella growth by keeping water systems clean and free from contaminants and corrosion, which can serve as nutrient sources for bacteria. Routine inspections and cleaning of water tanks become imperative, especially upon detecting debris or contamination, to ensure the health and safety of building occupants.

Different water systems require different approaches. Gravity tank-fed systems, frequent in commercial properties, often employ Glass Reinforced Plastic (GRP) tanks. These tanks, while durable, may deteriorate over time, manifesting issues like stress cracking or rusty bolts. Thorough inspection and maintenance protocols become essential in preserving the integrity of these systems.

Cleaning and disinfection methods vary, with chemical disinfection being a primary recommendation. Pre-disinfection may be warranted in certain scenarios, such as the presence of contaminants like dead organisms or pigeon excrement in the tank. Ensuring the thorough distribution of disinfectant to all outlets within the system, including showers and taps, is paramount to achieve comprehensive disinfection and mitigate risks effectively.

Understanding when to clean and disinfect tanks is equally crucial. Regular monitoring and risk assessments should prompt cleaning if the tank contains debris, sludge, scale, or traces of vermin. Tanks storing drinking water should undergo annual cleaning, and any alterations to the tank or pipework systems should prompt thorough disinfection to prevent contamination. Refer to page 26 of the HSG274 for easy to follow guidance

Understanding the Varieties Found Within Buildings

Within the intricate framework of building infrastructure, water systems play a pivotal role in ensuring the smooth functioning of various operations. Understanding the diverse types of water systems found within buildings is crucial for effective maintenance and management.

Systems Fed Directly from the Mains:

These systems draw water directly from the public water supply, providing a convenient and reliable source of water for building occupants.

Gravity Tank-Fed Systems:

Gravity tank-fed systems involve tanks positioned above the outlets, typically located in attic spaces or dedicated tank rooms on the roof. In tall buildings or areas with insufficient mains pressure, gravity tanks ensure a steady flow of water by utilizing gravity to create pressure. Boosted water systems, which employ pumps to strengthen water pressure, are a common feature in gravity tank-fed setups.

GRP Tanks – Glass Reinforced Plastic:

Among the most frequent types of tanks found in commercial properties, GRP tanks boast durability and versatility.

Despite their durability, sectional GRP tanks may develop leaks after being drained and refilled. This occurs due to the water pressure inside the tank, which pushes the seals together. Leaks typically manifest at the mating face between the walls and base panels, requiring prompt attention to prevent water wastage and potential damage.

Managing Tank Deterioration:

Stress Cracking:

An increasing issue observed in Glass Reinforced Plastic (GRP) tanks is stress cracking. These cracks typically manifest internally on the lip of panels and signal the end of the tank’s life cycle. Stress cracking compromises the structural integrity of the tank, leading to potential leaks upon refilling. While tank lining may temporarily address small leaks, the ultimate solution lies in tank replacement to prevent further damage and ensure long-term reliability.

Rusty Bolts:

Rusty bolts within GRP tanks often indicate underlying issues stemming from incorrect installation practices or exposure to disinfectants like chlorine. Incorrect bolt usage, where galvanized bolts intended for dry external flanges are mistakenly used for wetted surfaces, can accelerate rust formation. Additionally, chlorine exposure during disinfection processes can rapidly corrode stainless steel bolts. Thorough rinsing of surfaces above the water line post-disinfection is crucial to mitigate corrosion risks.

Capacity and Design:

Understanding the capacity and design of tanks is fundamental for maintenance personnel. Generic terms like “50-gallon tanks” denote common domestic plastic tanks, which come in various designs, some easier to clean than others. Poorly fitting lids and insulation can exacerbate issues like airlocks, affecting the tank’s functionality. Ensuring accurate measurement of tank capacity and awareness of design nuances are crucial for effective maintenance planning and execution.

Legionella Safety – Importance of a Written Scheme of Control

In the fast-paced and dynamic sports industry, ensuring the safety and well-being of athletes, staff, and visitors is of utmost importance. One critical aspect of maintaining a safe environment is the effective management of water systems to prevent the growth and spread of Legionella bacteria. This blog post highlights the significance of a comprehensive Written Scheme of Control and its role in safeguarding the sports industry against Legionella risks.

Understanding the Written Scheme of Control:

A Written Scheme of Control is a vital risk management document that outlines the measures necessary to control the risk of Legionella exposure in water systems. It provides clear guidance on implementing and managing these measures to ensure water system safety.

Roles and Responsibilities:

The first crucial element of a Written Scheme of Control is defining the roles and responsibilities of key personnel within the sports organization. This includes identifying the overall responsible person and statutory site duty holder who hold ultimate responsibility for the safety of all individuals within the sports community. Additionally, it specifies the person in charge of the day-to-day implementation of the Legionella control policy.

Risk Identification and Control Measures:

The Written Scheme of Control should comprehensively address the risks associated with Legionella and outline the specific control tasks that will be implemented. This involves identifying potential sources of Legionella contamination, such as cooling towers, showers, and other water systems present in the sports facility. The document then describes the control measures that will be employed to mitigate these risks effectively.

Water Hygiene Provider Contact Details:

If applicable, the Written Scheme of Control should include contact information for the water hygiene provider responsible for supporting the organization in implementing the control measures. This ensures that the sports facility can seek expert assistance and guidance whenever necessary.

Record Keeping:

Accurate record keeping is crucial for monitoring and maintaining water system safety. The Written Scheme of Control should outline the procedures and requirements for record keeping, including documentation of regular inspections, maintenance activities, and any remedial actions taken.

Audit and Noncompliance Escalation:

To ensure the ongoing effectiveness of the control regime, regular audits of the Legionella control measures should be conducted. The Written Scheme of Control should detail the audit process, including how noncompliance issues will be addressed and escalated within the organization.

Schematic Drawing:

Including a schematic drawing of the water systems within the sports facility can be highly beneficial. This visual representation helps stakeholders better understand the layout of the systems, aiding in the identification of potential risks and facilitating effective control measures.

Plant Shutdown Procedures:

In the event of maintenance or emergency situations, clear procedures for the shutdown and commissioning of water systems should be documented. The Written Scheme of Control should outline the steps to be followed to ensure proper shutdown and safe restart of the systems.

Risk Assessment Review Procedure:

Regular review of the Legionella risk assessment is essential to ensure that control measures remain up to date and relevant. The Written Scheme of Control should outline the procedure for conducting periodic reviews and any necessary updates to the control measures based on new information or changing circumstances.

Emergency Procedures:

The Written Scheme of Control should include detailed emergency procedures to be followed in the event of a suspected or confirmed outbreak of Legionella. This ensures that the organization can respond promptly and effectively, minimizing the impact of the outbreak on the sports community.

A robust Written Scheme of Control is a vital tool for the sports industry to manage and mitigate the risks associated with Legionella in water systems. By clearly defining roles and responsibilities, outlining control measures, and providing procedures for various scenarios, sports organizations can ensure the safety of athletes, staff, and visitors. Regular review and adherence to the Written Scheme of Control are essential for maintaining water system safety and protecting the well-being of all individuals involved in the sports industry.

It is their responsibility to review the template and make any necessary amendments to accurately reflect how your organization operates in managing the control scheme for Legionella risk. By taking ownership of the document, you can ensure that it aligns with your organization’s practices and procedures.

Key Components of the Template:

Our written scheme of control template covers all the necessary elements to prevent the growth and proliferation of Legionella bacteria. It clearly specifies the control measures required, providing a comprehensive framework for managing Legionella risks. Additionally, the template describes the procedures for implementing and executing these control measures, ensuring consistency in their application. It also outlines how your organization will allocate and manage the control tasks, ensuring clear responsibilities and accountability.

Referring to HSG274 Part 2:

For a summary of the requirements of a written scheme, we encourage you to refer to appendix 2.2, page 55, of HSG274 Part 2. This publication by the Health and Safety Executive (HSE) provides valuable insights and guidance to complement our template, ensuring that you are well-informed and compliant with the relevant standards.

Completion of Blue Text Fields:

To personalize the written scheme of the control template, certain fields are highlighted in blue text. It is the responsibility of the responsible person or statutory duty holder within your organization to complete these fields, ensuring that the document accurately reflects your specific operations and procedures.

Managing Legionella Safety in the Sports Industry requires a systematic and tailored approach.
